FIELD OF INVENTION

The present invention relates to a recliner.

BACKGROUND OF INVENTION

U.S. Pat. No. 5,186,518 discloses a conventional recliner. Thisconventional recliner is however very complicated in structure. Thiscomplicated structure includes many parts and eventually entails a veryhigh cost. Moreover, this complicated structure is bulky and heavy. Thepresent invention is therefore intended to obviate or at least alleviatethe problems encountered in prior art.

SUMMARY OF INVENTION

It is an objective of the present invention to provide a recliner with abackrest that can be moved to any desired position within a range.

It is an objective of the present invention to provide a recliner with astool that can be moved to any desired position within a range.

It is another objective of the present invention to provide a reclinerthat is simple in structure.

According to the present invention, a recliner includes two frames, abackrest frame pivotally attached to the frames, a stool frame pivotallyattached to the frames, a link connected between the backrest frame andthe stool frame and a hydraulic cylinder connected between one of theframes and the backrest frame.

Other objects, advantages and novel features of the invention willbecome more apparent from the following detailed description inconjunction with the attached drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIG. 1 shows the profile of a recliner 10 according to the preferredembodiment of the present invention.

Referring to FIG. 2, a structure of the recliner 10 is shown. Therecliner 10 includes two frames 20, a backrest frame 30, a stool frame40, two links 50 and a hydraulic cylinder 60.

Each frame 20 includes an upper member used as an armrest and a lowermember used as a foot. The frames 20 are preferably made of wood inconsideration of weight. A beam 21 is attached to each frame 20. Thebeams 21 are preferably made of metal in consideration of strength. Aplurality of springs 22 is connected between the frames 20 in order tosupport a seat (not shown). A crossbar 23 is connected between theframes 20.

The backrest frame 30 includes two links 31 and two crossbars 32connected between the links 31. Each link 31 is pivotally attached tocorresponding one of the beams 21. The pivotal of the links 31 arelimited by means of the crossbar 23. Each link 31 includes an uppersection and a lower section. Although not shown, a backrest plate isattached to the upper sections of the links 31, and sponge is attachedto the backrest plate.

The stool frame 40 includes two links 41. Each link 41 includes an uppersection and a lower section. The lower section of each link 41 ispivotally attached to corresponding one of the frames 20.

Each link 50 is connected between the lower section of one of the links31 and the lower section of corresponding one of the links 41. Althoughnot shown, a stool plate is attached to the links 41, and sponge isattached to the stool plate.

The hydraulic cylinder 60 includes an end attached to one of the frames20 and an opposite end attached to the lower section of one of the links31. The hydraulic cylinder 60 includes a lever 61 for the controlthereof. The lever 61 can be pivoted between a first position as shownin FIG. 3 and a second position as shown in FIG. 5. When the lever 61 isin the first position, the hydraulic cylinder 60 cannot be extended andshrunk. When the lever 61 is in the second-position, the hydrauliccylinder 60 can be extended and shrunk.

Referring to FIG. 3, the lever 61 is in the first position. Thehydraulic cylinder 60 cannot be extended and shrunk. Referring to FIG.4, the backrest frame 30 is in a high position. The backrest frame 30 isretained in the high position by means of the hydraulic cylinder 60 asthe lever 61 is in the first position.

Referring to FIG. 5, the lever 61 is in the second position. Thehydraulic cylinder 60 can be extended and shrunk. Thus, the backrestframe 30 can be pivoted down to a position as shown in FIG. 6. Thebackrest frame 30 can further be pivoted down to a position as shown inFIG. 7. The backrest frame 30 can be pivoted to any desired positionwithin a range. The backrest frame 30 can be retained in position bymeans of the hydraulic cylinder 60 when the lever 61 is released andturned back to the first position.

The present invention has been described via detailed illustration ofthe preferred embodiment. Those skilled in the art can derive variationsfrom the preferred embodiment without departing from the scope of thepresent invention. Therefore, the preferred embodiment shall not limitthe scope of the present invention defined in the claims.
